Biocidal isothiazolinone or isothiazolothione compounds are stabilized with an effective amount of a free-radical scavenger compound. Exemplary of the biocidal isothiazolones are 1,2-benzisothiazolin-3-one, 2 methyl-4-5-trimethylene-4-isothiazolin-3-one, chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one. Effective free-radical scavengers include 3,3-trhiodipropionic acid, L-ascorbic acid, D-ascorbic acid, fumaric acid, diethylhydroxylamine, glutaraldehyde, butyraldehyde, L-tartaric acid, 4-methoxyphenol and propyl gallate.
